Tunnel lighting

túnel-bielsaThe primary objectives of tunnel lighting is to ensure traffic safety by illuminating all important objects during the journey of vehicles, and to improve visibility and comfort. Proper lighting in road tunnels will ensure that traffic can enter, pass through and leave the tunnel with a great level of safety. These aims are achieved by the adequate illumination of the tunnel interior, which allows drivers to quickly adjust to the light within, identify possible obstacles, and manage to leave the tunnel without reducing speed.

For that purpose, it is compulsory that the carriageway and the tunnel walls give a clear picture of the road. The road markings and stripes should also be visible, and tunnel lighting should ensure that objects on the road are visible at a sufficient distance.

Lighting must then ensure an adequate luminance level on the road, throughout the tunnel, and that luminance ha to be distributed uniformly on the road, in wet or in dry conditions. The lighting should not give rise to glare. Read more

Lighting in parking lots and car parks

A well-lighted parking lot is a key pointlighting car park for a shopping center or a building. Well-lighted car parks do attract customers, improve traffic, as well as the safety of pedestrians. A parking lot that lacks efficient lighting may result in wasted energy, low pedestrian security, and less attractiveness, which may affect your commercial results. For these reasons, choosing the right light fixtures will result in positive effects for any parking lot.

A number of issues can arise in car park lighting applications, such as light loss that occurs due to lamp depreciation and the usual wear of the components of the light fixture. Light loss can also take place when external elements such as dirt and moisture break into into the housing and accumulate on surfaces of the light fitting, which may result in lower light efficiency. Another common issue in lighting of parking lots is related to light distribution. A luminaire’s vertical and lateral light distribution can affect the quality of the lighting installation of the car park. For instance, horizontal and vertical illuminances which are below recommended practices may reduce the visibility of approaching vehicles or pedestrians. Horizontal illuminance uniformity is important in parking lots for both comfort and safety reasons, and you will have to select the appropriate luminaire based on the required illuminance uniformity on the ground.

Lighting solutions for educational facilities, schools, universities, institutions

lighting education

Lighting at school should provide a high visual comfort by ensuring an adequate and appropriate illumination level and strictly preventing the risk of glare. Lighting system has to respect the legal standards especially safety standards for electrical equipment, and to enable the rational use of energy by promoting the highest energy efficiency.

When designing the lighting system for educational facilities, the designer has to pay attention to important criteria which affect the quality of the overall lighting solution:

– Colour temperature:

The colour temperature of a light source is a numerical measurement of its colour appearance. This temperature is expressed in Kelvin degrees. Colours and light sources from the violet/blue end of the spectrum are referred to as “cool,” and those toward the red/orange/yellow side are “warm”. Light colour may affect the mood, and learning behaviour. Cool light lamps will provide similar outdoor environment, which may help some students who can’t stand staying inside for hours, while warm colours lamps will provide a more relaxed, non-threatening learning environment. A colour temperature between 3000–4000K is generally recommended for classrooms

– Light quality:

The Colour Rendering Index (CRI) expresses the quality of light. The CRI is a scale from 0 to 100 percent indicating how truthfully the individual light sources are able to copy the colouring of the object compared to the natural daylight. The higher the CRI the more faithful the colour reproduction. Light sources with a colour rendering index above 85 are recommended for classrooms.

– Energy efficiency:

Energy-efficient lighting directly affects lighting costs. By selecting efficient lamps the number of fixtures required in a school can be reduced. To calculate the total lighting costs, you should consider beyond the purchase price the average maintenance costs (cleaning, lamp replacement).

Energy savings:

Lighting can be an area for large gains in energy efficiency savings. The figures show that inefficient lighting systems in classrooms may represent 50 to 70% of electricity bills in many school facilities. Airfal offers efficient lighting solutions that help reduce energy costs while providing high quality illumination for students and teachers. Airfal lighting solutions for educational facilities (schools or universities) improve the feeling of well-being of the pupils and teachers, providing visual comfort and eye-protection that promote effective classroom teaching and learning in friendly and stimulating atmosphere.

Lighting fixtures for gas stations

petrol pump luminaireLighting is a key factor for the proper functioning and the commercial success of a gas station. Lighting will guide your customers in the service station safely and with maximum visual comfort. Access and parking areas should be properly lighted, giving motorists a first impression of the station. Good lighting will help create an atmosphere conveying safety and quality. Researchers have found that the number of drivers turning into a gas-station and consequently the turnover of the business is affected by the quality of light. Better lighting encourages drivers to use a gas-station. Naturally, people are drawn to businesses that give a stronger sense of cleanliness, friendly service and an environment that feels safe and secure. A side effect of this tendency are the increased energy expenditures.

Lighting and fixtures must be designed to improve the energy efficiency of the petrol station. The costs related to lighting can significantly impact the financial results of your service station. In many cases, installation of an efficient lighting system will result in a significant reduction in energy consumption. Read more

Lighting in offices and workplaces

luminaria oficina

In the past, fluorescent tubes were used to illuminate workplaces, resulting sometimes in cold atmospheres, and inefficient lighting. Today, we must take into account multiples factors, including the quality of light, luminous efficiency (how well a light source produces visible light), the design of the lights , and  energy efficiency.

If lighting at the office is not adequate, the workers may get tired quicker, with more visual fatigue, which may affect their performance. To optimize work efficiency, we will therefore have to choose the right lighting. Not only does the lighting system must guarantee visual comfort, it must also contribute to create a pleasant lighting atmosphere in the office. To boost productivity of employees, a high level of illumination is required at the office. This is essential, since a physical and psychological well-being result in higher productivity.

For efficient lighting, we must take into account the activity undertaken.  Lighting levels should match the workplace and the work tasks being performed. The different areas which will be illuminated, the number of jobs, will also influence the lighting system and the quality of natural light, as well as the energy consumption induced. The laws and specific rules for office lighting should also be taken into account.

Visual comfort is influenced by many aspects of lighting . Proper lighting makes all work tasks easier. People receive about 85 percent of their information through their sense of sight. Appropriate lighting, without glare or shadows, can reduce eye fatigue and headaches at the office. Direct glare from the lights makes it difficult to work with computer, and over time can cause eye irritation to the employee . The ambient lighting usec should be low or glare free. Indirect or direct/indirect light fixtures provide the best lighting solutions for many offices. This kind of light fixture hangs from the ceiling and gives more even illumination. The office should be arranged to minimize glare from overhead lights, desk lamps, and windows. Excessive contrasts cause also variations in the adaptation of the eye , which slows down the work and result in errors .

Generally speaking , the minimum levels of lighting in the workplace are defined by regulations.  These levels are measured with a light meter and expressed in lux , and this lighting unit is produced by a lumen ( amount of light emitted by a light source ) on a square meter of surface. The CIBSE Code for Lighting recommends a maintained luminance of 500 lux for general offices (e.g. writing, typing, reading, data processing, etc.) and for CAD work stations and conference/meetings rooms. Where the main task is less demanding, e.g. filing, a lower level of 300 lux is recommended. 

Although it is recommended to have natural light in offices, there is no minimum requirement. But no natural light throughout the day ensures uniform lighting , and therefore it is recommended for to combine direct and indirect lighting in offices. To achieve this double exposure to direct and indirect light, we should use different light fixtures. For example, direct light from the ceiling ( neon tubes or LED lighting integrated in the roof ) can be completed with indirect lighting (desk lamps , wall … ) .

How to manage lighting for hazardous areas ?

atmosfera explosible

A hazardous area is defined as any place in which an explosive atmosphere may occur. Hazardous areas may exist due to flammable gases or vapours or combustible dust. Explosions can cause loss of life and serious injuries as well as extensive damage. If there is enough quantity of flammable substance (the fuel) mixed with oxygen (the oxidizer), an ignition source (e.g. an electric spark) is sufficient to cause an explosion, in which combustion spreads to the entire mixture yet unburned, and can be caused by unadapted light fixtures.

Where can explosive atmospheres be found?

Many workplaces may develop or have activities that produce explosive or potentially explosive atmospheres. Examples include places where work activities create or release flammable gases or vapours, such as:

– Vehicle paint spraying,

– Metal processing facilities, where explosive metal dusts may form.

– Processing units of raw materials that generate fine organic dusts such as grain flour or wood manufacturing units.

The potential for explosive atmospheres can exist in a range of mainly industrial locations such as mines, factories, agricultural silos, and oil and gas platforms, water and other chemical processing environments.  There is a wide range of products intended for use in such areas, including control equipment and sensors, transformers, fans, pumps, compressors, fork lift trucks, and lighting.
